Proposed all-versus-nothing violation of local realism in the Kitaev spin-lattice model
Ming-Guang Hu, Dong-Ling Deng, Jing-Ling Chen
We investigate the nonlocal property of the fractional statistics in Kitaev's toric code model. To this end, we construct the Greenberger-Horne-Zeilinger paradox which builds a dir…
Exact Solution of a Yang-Baxter Spin-1/2 Chain Model and Quantum Entanglement
Ming-Guang Hu, Kang Xue, Mo-Lin Ge
Entanglement is believed to be crucial in macroscopic physical systems for understanding the collective quantum phenomena such as quantum phase transitions. We start from and solve…
Geometric phase of a two-level system in a dissipative environment
Kazuo Fujikawa, Ming-Guang Hu
The geometric (Berry) phase of a two-level system in a dissipative environment is analyzed by using the second-quantized formulation, which provides a unified and gauge-invariant t…
Gisin's theorem for two d-dimensional systems based on the Collins-Gisin-Linden-Masser-Popescu inequality
Jing-Ling Chen, Dong-Ling Deng, Ming-Guang Hu
In this Rapid Communication, we show analytically that all pure entangled states of two d-dimensional systems (qudits) violate the Collins-Gisin-Linden-Masser-Popoescu (CGLMP) ineq…
